Analytical Chemistry Mon, 10 Oct 2016 09:11:28 ESTnews395309479Initiating DNA repairTo find out what activates SIRT6, the researchers alternately applied chemical inhibitors to human skin cells to determine which proteins were essential in getting the gene to repair the broken DNA strands. They discovered that one protein was involved in activating the gene in response to oxidative stress—c-Jun N-terminal kinase, which goes by the simpler term JNK. When JNK was inhibited, SIRT6 was not activated and the broken strands of DNA were not repaired efficiently.http://phys.org/news/2016-09-dna.html

Biochemistry Thu, 02 Jun 2016 09:42:44 ESTnews384079356Trojan horses for hospital bugsStaphylococcus aureus is a bacterium that is frequently found on the human skin and in the nose where it usually behaves inconspicuously. However, once inside the body, it can have life-threatening consequences such as abscesses, sepsis, pneumonia or myocarditis. How the pathogen manages to perform its disastrous work is still largely in the dark despite intensive research. Scientists from the Universities of Oxford and Würzburg have now unravelled an equally puzzling phenomenon. They present their results in the latest issue of the scientific journal PNAS.http://phys.org/news/2016-05-trojan-horses-hospital-bugs.html

Biotechnology Thu, 10 Sep 2015 12:00:03 ESTnews361104667A goosebump sensor that reads your emotionsPeople get goosebumps when they feel a sudden surge of emotion. Goosebumps are due to the shrinkage of the skin cells around hairs, making the hairs stand on end. Animals, such as lions and cats, develop the goosebumps or "piloerection", and the hair standing on end makes them appear larger or stronger, especially when they feel fear or anger. Human skin also develops goosebumps on instinct when a person experiences a sudden change of emotion.http://phys.org/news/2015-06-goosebump-sensor-emotions.html

Cell & Microbiology Thu, 17 Jul 2014 16:09:54 ESTnews324832182A new molecule for high-resolution cell imagingLike our own bodies, cells have their own skeletons called 'cytoskeletons' and are made of proteins instead of bones. These network-like structures maintain the cell's shape, provide mechanical support, and are involved in critical processes of the cell's lifecycle. The cytoskeleton is an object of intense scientific and medical research, which often requires being able to observe it directly in cells. Ideally, this would involve highly-fluorescent molecules that can bind cytoskeletal proteins with high specificity without being toxic to the cell.http://phys.org/news/2014-05-molecule-high-resolution-cell-imaging.html

Cell & Microbiology Thu, 05 Dec 2013 12:01:25 ESTnews305467027Scientists isolate new human pluripotent stem cellsOne of the obstacles to employing human embryonic stem cells for medical use lies in their very promise: They are born to rapidly differentiate into other cell types. Until now, scientists have not been able to efficiently keep embryonic stem cells in their pristine stem state. The alternative that has been proposed to embryonic stem cells – reprogrammed adult cells called induced pluripotent stem cells (iPS cells) – have similar limitations. Though these can differentiate into many different cell types, they retain signs of "priming," – commitment to specific cell lineages.http://phys.org/news/2013-10-scientists-isolate-human-pluripotent-stem.html
